/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...
1.analogRead ( pin ) : ① 模拟输入引脚是带有ADC(Analog-to-Digital Converter,模数转换器)功能的引脚。 ②它可以将外部输入的模拟信号转换为芯片运算时可以识别的数字信号,从而实现读入模拟值的功能。 ③模拟输入功能需要使用analogRead() 函数。 参数:参数pin是指定要读取模拟值的引脚,被指定的引脚必须是模拟输入...
2.先来学习Arduino模拟输入输出功能的函数。模拟输入引脚是带有ADC(Analog-to-Digital Converter,模数转换器)功能的引脚。它可以将外部输入的模拟信号转换为芯片运算时可以识别的数字信号,从而实现读入模拟值的功能。模拟输入功能需要使用AnalogRead() 函数。使用之前并不需要另外配置引脚为模拟输入或输出模式,因为在该函数...

center pin of the potentiometer to the analog input 0 one side pin (either one) to ground the other side pin to +5V - LED anode (long leg) attached to digital output 13 cathode (short leg) attached to ground - Note: because most Arduinos have a built-in LED attached to pin 13 on...
int analogPin = 5;int val = 0;void setup(){Serial.begin(9600);}void loop(){val = analogRead(analogPin);Serial.println(val);}这里还是要实现Matlab的即时读取和画图。Matlab代码如下:s = serial('COM3'); %定义串口对象set(s,'BaudRate',9600); %设置波特率sfopen(s); %打开串口对象sinterval...
